Arstillfurther object of this inventionV is, the provision cia rigidnoyel'd'isc-lilie securing Ymeans for the I textile material'.`

In assembling'mynovel buin'gwheel Ill, two identical discs I5 are placedback-to-back, (see. Figx) soV that'jthe'centralopeningsIBand'eccentrically disposed openings '2 I' 'of' each coincide.y

The'l discs l5 comprise three main '-p'ortionsyan inner 3 The two discsare then joined together into a single unit, by any suitable means, forexample, by spot welding, as indicated at 3I in Fig. 2 o1' by riveting,etc.

The folded fabric II is brought into contact by known means with thejoined discs; the outer portion of the joined discs is opened up so asto receive the inner edge of the folded fabric Il, and the teeth 21 arecaused to be clamped into the fabric so that each tooth tip 28 engagesthe low point 32 of a fold I4. Because of the unique structure of thejoined discs the teeth of one of the joined discs will be in staggeredrelation with the corresponding teeth of the other joined disc, thedistance between the teeth in clamped relation being one half thedistance between adjacent teeth on each of the joined discs. Also, theholes 24 0f one of the joined discs will be in staggered relation withcorresponding holes 24 of the other disc.

I have found it advantageous so to attach the joined discs to thetextile material as to permit an annular channel 22 to exist between theholes 24 of the joined discs and the inner peripheral edge I3 of thetextile material. This perhaps can be best noted from Fig. 3.

By reason of the fact that the eccentrically-located holes 2l extendbeyond the walls I9 of the disc I a passage for air ow is formed throughthe eccentrically-located holes 2| into the channel 22 and out of thesmall holes 24 in the outer portion of the disc, thereby obtaining acooling effect which is desirable in bufling devices.

While I have described my invention in detail in its preferredembodiment, it will be obvious to those skilled in the art, afterunderstanding my invention, that various changes and modifications maybe made therein without departing from the spirit or scope thereof. Iaim in the appended claims to cover all such modifications and changes.
